Scars Like Wings by Chelsey J. Leon

When I was little, Mom would tell it to me like a fairytale, a story that couldn’t be real. Little did I know how real the monsters were. And I’m not talking about the dragons.

When her mother was murdered, Byrd Pierce’s world shattered. She lost so much, so young and she feared she’d never be able to recover. Years later, Byrd had not only picked up the pieces but had also mended them with gold. She has a job at a living magical library, a witch and a mermaid for best friends, and a closet with clothing that not only flatters her plus-size body but also makes her look hot AF.
When Quinn Garcia literally falls head over heels for her, Byrd thinks she’s finally found her “okay” at last. But when Quinn compliments a back tattoo only she can see -one she doesn’t actually have, at that- everything shifts. While trying to research the mysterious tattoo, Byrd finds a book that only she can open, containing one single sentence written in her mother’s handwriting: Are you ready to know the truth, Baby Byrd?
Suddenly, the mysteries surface and threaten to drown Byrd. Nothing from her friends to her past to Quinn is what they have always seemed. The further she dives, however, the more one solitary idea becomes clear: her mother did everything to keep her safe. But at what cost?
